This model performs a transient analysis of the temperature through a house wall. The wall is formed of different layers corresponding to the structure, insulation and plaster. On the exterior and the interior, the wall is exposed to thermal radiation and convective cooling. The results ... Mehr lesen
This example exemplifies how curve fitting can be performed in COMSOL Multiphysics®, and how this can be applied to your modeling. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Curve Fitting of Experimental Data with COMSOL ... Mehr lesen
Helmholtz resonators are used in exhaust systems, as they can attenuate a specific narrow frequency band. The presence of a flow in the system alters the acoustic properties of the resonator and the transmission loss of the subsystem. In this tutorial model, a Helmholtz resonator is ... Mehr lesen
One of the ways we can simplify and reduce the size and computational complexity of a finite element model is by using any symmetries present in a model. In this entry, you can find three practical examples highlighting how to exploit symmetries in RF or wave optics modeling. They all ... Mehr lesen
A plane electromagnetic wave is incident on a metallic sphere partially embedded on a substrate. In this electromagnetic scattering problem, the far-field variables are computed for a few elevation angles of incidence. Mehr lesen
This model demonstrates three different ways to find the eigenfrequencies of a rectangular metallic cavity. The first method uses an eigenfrequency study step together with the Electromagnetic Waves, Beam Envelopes interface. Here, it is important to define a wave vector for the physics ... Mehr lesen
In this example, the etching of silicon in a CF4/O2 plasma reactor is studied using a global model. Parametric sweeps for ion energy and oxygen mole fraction are computed. Mehr lesen
In electromagnetic simulations, such as transformers and converter stations, one often needs to include geometrically thin conductive layers. Explicitly meshing these thin layers can be computationally expensive and numerically challenging, especially when the layer thickness is much ... Mehr lesen
This model demonstrates two ways of modeling waveguides that support multiple modes. A PML can be used to absorb any modes, or Ports can be explicitly added for each possible mode. Learn more in this accompanying blog post: Modeling Waveguides that Support Multiple Modes Mehr lesen
Tesla microvalves exploit the non-linear nature of inertial flow to create anisotropic flow resistance. They can be used as robust valves owing to their passive working mechanism, but for many applications the diodicity is too low. Two-dimensional simulations and optimization over ... Mehr lesen
